The third execution mode may be a mode for displaying the executionresult of the application corresponding to the object on a separatewindow. In the third execution mode, the execution result of theapplication corresponding to the object may be displayed on a separatepop-up window.

The exemplary embodiments will now be described more fully withreference to the accompanying drawings, in which exemplary embodimentsare shown.

FIG. 1 is a diagram of a case where an object is executed on a displayof a device by using a method of executing an object, according to anexemplary embodiment.

As shown in FIG. 1, a predetermined object may be displayed on a screenof the device according to the present embodiment and the object may beselected by a user touch. The object refers to an object that may beselected by a user input. The object includes an image, a text, and avideo, and for example, an icon, an index item, link information, areproduced image of contents, and so on. For example, the object on thescreen of the device may include, but is not limited to, an icon of avideo file, an icon of a music file, an icon of video reproducingapplication, an icon of music reproducing application, weatherinformation providing widget, and calendar widget.

According to a user input for selecting the object, one of a pluralityof execution modes may be determined, and an operation of the device,which corresponds to the object, is performed according to thedetermined execution mode. As the object is enlarged according to a userinput, the execution result of application corresponding to the objectmay be displayed may be gradually enlarged.

FIG. 2 is a flowchart of a method of executing an object, according toan exemplary embodiment.

In operation S200, a device receives a user input to an object. Inoperation S200, the device may receive the user input through a touchscreen. Here, a touch input may be formed by at least one gesture oftouch, hold, tap, drag, flick, pinching, and unpinching. The user inputis not limited to the touch input, and may include a voice input and agesture for moving the device.

In operation S210, the device determines one from among a plurality ofexecution modes according to the user input. A plurality of executionmodes of the device may be set so as to perform different operationswith respect to an object according to the user input of the object.

The plurality of execution modes may include, but are not limited to, atleast one of a first execution mode, a second execution mode, and athird execution mode.

The first execution mode may be a mode in which an operation formanaging an object on a display is executed. For example, in firstexecution mode, at least one of selecting, copying, cutting, and movingthe object may be performed.

The second execution mode may be an execution mode for executingapplication corresponding to the object while enlarging the object. Forexample, in the second execution mode, as the object is graduallyenlarged by a user input and the application corresponding to the objectmay be executed, the execution result of the application may bedisplayed on a region of the gradually enlarged object.

The third execution mode may be a mode for displaying the executionresult of the application corresponding to the object on a separatewindow. In the third execution mode, the execution result of theapplication corresponding to the object may be displayed on a separatepop-up window.

The first, second, and third execution modes may be matched withrespective user inputs. For example, a user input performed by touchingan object for a predetermined period of time or more may be matched withthe first execution mode.

In addition, for example, a user input performed by touching an objectfor a predetermined period of time or more and then dragging the objectmay be matched with the second execution mode. In this case, as an edgeportion of the object is touched and is dragged, applicationcorresponding to the object may be executed according to the secondexecution mode. For example, a user input performed by pinching anobject may be matched with the second execution mode. In addition, forexample, a user input performed by touching an object a predeterminednumber of times within a predetermined period of time may be matchedwith the third execution mode. However, the exemplary embodiment is notlimited thereto.

In operation S220, the device executes application corresponding to theobject according to the determined execution mode. In operation S220,the device may perform an operation corresponding to the objectaccording to the execution mode matched with a user input. For example,when the object is an execution icon of weather application, the devicemay execute weather application. In addition, for example, when theobject is a link item for accessing a predetermined website, the devicemay execute an Internet browser.

In operation S230, the device terminates an operation corresponding tothe object according to a user input. In operation S230, as the objectis touched and dragged and then the object is dropped within apredetermined period of time, the device may terminate the operationcorresponding to the object. In addition, as a user input, which isperformed by touching and dragging the object and then flicking (ordragging) the object in an opposite direction to a direction in whichthe object is enlarged while the touch is maintained, is input, thedevice may terminate execution of the operation corresponding to theobject. In addition, as the object terminates the operation, the devicemay reduce the enlarged object to an original size and may display theobject.

In addition, the enlarged object may be reduced according to apredetermined user input. For example, when a user selects awindow-close-icon displayed on the region of the enlarged object, theenlarged object may be reduced. Alternatively, for example, when theuser touches the enlarged object for a predetermined period of time ormore, moves the touched object to a predetermined region (for example, aregion where a trash box icon) by dragging the object, and drops theobject, the object may be restored to an original state. Alternatively,for example, when the user unpinches the enlarged object, the enlargedobject may be reduced. Alternatively, for example, when a corner of theenlarged object is touched for a predetermined period of time and thenis dragged or flicked in a diagonal direction, the enlarged object maybe reduced. Alternatively, for example, when the user rubs the enlargedobject and wallpaper together, the enlarged object may be reduced.

FIG. 3 is a flowchart of a method of displaying an execution result ofan object according to a second execution mode, according to anexemplary embodiment.

In operation S300, a device enlarges an object according to a userinput. In operation S300, the device may enlarge the object in responseto a user input performed by touching and dragging the object within apredetermined period of time. For example, as an edge portion of theobject is touched and dragged, the object may be enlarged. In this case,the device may determine a degree at which the object is enlarged, basedon a distance between a position at which the object is touched and aposition at which the dragging is finished. Alternatively, for example,the object may be enlarged by a user input performed by pinching theobject.

In addition, the device may enlarge the object based on a user inputincluding two steps. The device may determine whether an enlargingfunction of the object is activated, based on a user input. After theenlarging function of the object is activated, when the device receivesa user input, the device may enlarge the object.

For example, when the object is touched and held for a predeterminedperiod of time or more, the enlarging function of the object may beactivated. Alternatively, for example, when a predetermined voice isinput to the device, the device may activate the enlarging function ofthe object. In this case, an enlarging size of the object andinformation displayed on the enlarged object may be previouslydetermined and the determined information may be displayed on the regionof the enlarged object having the determined size.

Alternatively, for example, when the object is multi-touched, theenlarging function of the object may be activated. Alternatively, whenthe object is touched and is dragged in a predetermined pattern (forexample, a circle, zigzag, etc.), the device may activate the enlargingfunction of the object. Alternatively, when a touch pressure of theobject is equal to or greater than a predetermined intensity, the devicemay activate the enlarging function of the object.

In addition, an effect for indicating that the enlarging function of theobject is activated to the user may be displayed. For example, when theenlarging function of the object is activated, a user interface (UI) fora predetermined operation (for example, an operation for enlarging theobject) may be displayed at a corner of the object. In addition, whenthe enlarging function of the object is activated, the object displayedon a display may shake or may be enlarged. Alternatively, when theenlarging function of the object is activated, the object may bedisplayed tridimensionally. For example, an edge of the object may bedisplayed thick or the region of the enlarged object may be displayedconcave inward of the display.

In addition, as the enlarging function of the object is activated, aseparate object to be enlarged according to a user input may begenerated and displayed. For example, when a first icon is touched andheld for a predetermined period of time or more, a second icon forexecuting application corresponding to the first icon may be generatedand displayed. In addition, the second icon may be an icon in which theenlarging function is activated.

In addition, the device may enlarge the object according to a user inputto an object of which an enlarging function is activated. For example,the device may enlarge the object according to a user input performed bya pinching input to the object of which the enlarging function isactivated. When the object is touched with at least one finger and isunpinched, the object may be enlarged. Alternatively, the object may beenlarged according to a user input performed by touching and unpinchinga region where the object on a display does not exist.

Alternatively, the object may be enlarged according to a user inputperformed by touching and dragging the object of which the enlargingfunction is activated. Alternatively, for example, the object may beenlarged according to a user input performed by touching a plurality ofnumber of times the object of which the enlarging function is activated.In this case, the object may be enlarged to a predetermined size.

In addition, for example, when a separate object to be enlarged isgenerated and displayed, the separate object may be enlarged to apredetermined size by touching the separate object.

In operation S310, the device may display the executing result ofapplication. In operation S310, the device may display the executingresult of application on a of the enlarged object. For example, as thedevice enlarges the object, the device may display the executing resultof application corresponding to the object on the region of the enlargedobject. In this case, as the application is enlarged, the executingresult of the application may be gradually enlarged and may bedisplayed. In addition, as the object is enlarged, some functions of theapplication may be performed.

For example, when the object is enlarged by touching and dragging theobject, when the device starts receiving a drag input, the executingresult of application may be displayed. In addition, after the draginput is received, when the object is dragged by a predetermineddistance or more, the executing of the application may be displayed.

In addition, information that is displayed as the executing result ofthe application may be obtained from application installed in thedevice, but the exemplary embodiment is not limited thereto. The devicemay receive information about execution of application from a separateserver and may display the received information. In this case, thedevice may be connected to the separate server and may receiveinformation about execution of application from the connected separateserver. In addition, the device may push a request for the informationabout execution of application to the separate server. If a networkingenvironment is unstable, when data receipt from a server is delayed, thedevice may display an image that is previously captured as an executingimage of application that is previously used, as the executing result ofapplication.

A method of receiving and displaying additional information about anobject from a server and content about the objet as the object isenlarged will be described in detail with reference to FIG. 9.

In addition, the device may receive information about execution ofapplication from another device (not shown) and may display the receivedinformation. In detail, as a predetermined object displayed on thedevice is enlarged, the device may be pared with another device (notshown), and the device may gradually receive partial information anddetailed information about content related to the object according tothe size of the enlarged object. For example, when an object forsearching for a file of the device is displayed on the device and isenlarged by a first threshold value or more, the device may receive anddisplay summary information of a file stored in another device (notshown) from another device (not shown). In addition, when the object isenlarged by a second threshold value or more, the device may receive anddisplay detailed information stored in another device (not shown) fromanother device (not shown).

In addition, the device may display the object together with theexecuting result of application on the region of the enlarged object,but the exemplary embodiment is not limited thereto.

In addition, the device may partially or entirely display the executingresult of application on the region of the enlarged object according tothe size of the enlarged object. In addition, the device may generate aplurality of images indicating the executing result of application andmay display the plurality of images according to the respective sizes ofthe enlarged object.

In addition, as the executing result of application is displayed,vibration of a predetermined pattern may be generated in the device.When the executing result of application is displayed on the region ofthe enlarged object, the executing result of application is emphasizedand displayed for a predetermined period of time. For example, whenexecuting result of application is displayed, the enlarged object ofwhich an edge is colored with a predetermined color blinks a pluralityof number of times for a predetermined period of time. Alternatively,for example, when the executing result of application is displayed, apredetermined sound may be output from the device. Alternatively, forexample, when the executing result of application is displayed, apredetermined smell may be generated. Alternatively, for example, whenthe executing result of application is displayed, shape of a surface ofthe device may be changed and a user may feel the change in the surfaceof the device via his or her sense of touch. In this case, the surfaceof the device may partially become convex or concave, but the exemplaryembodiment is not limited thereto.

In addition, the device may fix the region of the enlarged objectaccording to a user input and may display an executing result of anoperation corresponding to the object on the fixed object region. Forexample, after the object is touched and dragged, as the touch of theobject is held for a predetermined period of time or more, the devicemay fix the size of the enlarged object and may display the executingresult of the operation corresponding to the object on the fixed region.Alternatively, for example, after the object is touched and dragged, thedevice may detect a pressure applied by touching a display. When thedetected pressure is equal to or greater than a predetermined value, thedevice may fix the size of the enlarged object.

When the object is an icon for executing a predetermined content file,information contained in the executing result of application may varyaccording to a type of the content file.

For example, when the content file is a picture file, information abouta picture image, a picture photographing time, a picture photographingplace, and a picture photographing resolution may be contained in theexecuting result of application corresponding to the picture file.

In addition, for example, when the content file is a video file,information about an encoding method, a play time, and a videoresolution may be contained in the executing result of applicationcorresponding to the video file.

In addition, for example, when the content file is a music file,information about an encoding method and a play time, and albuminformation may be contained in the executing result of applicationcorresponding to the music file.

In addition, for example, when the content file is an applicationinstallation package file, a type of a platform which is subject toinstallation, application information, user evaluating information ofapplication may be contained in the executing result of applicationcorresponding to the application installation package file.

In addition, when the object is a folder icon, information about iconsof files included in the folder and folder information may be containedin the executing result of application corresponding to the folderinformation.

As the object is enlarged, the positions and arrangements of the otherobjects other than the enlarged object may be adjusted on the display.The other objects other than the enlarged object may be arranged outsidethe region of the enlarged object on the display. However, the exemplaryembodiment is not limited thereto. The enlarged object may overlap theother objects and may be displayed.
